Aging and weathering factors can affect the color of all window frame and hardware materials. AAMA has established and industry color standard for what is and isn’t acceptable.
AAMA/Industry Color Standard
- Some degree of color change is built into industry standards.
- Color change tolerances are covered by AAMA standards for painted aluminum, PVC, and other finishes.
- These standards take into account natural aging and weathering factors and describe the allowable change in ways that can be scientifically measured.
- As an example, in the chart below, the potential color change along one spectrum shows the point at which the AAMA standard for white PVC is set.
- PVC that passes the AAMA standard for window profiles meets this color change standard.
